Rapid prototyping/3D printing

Has anyone used rapid prototyping/3D printing when scratch building a project? Which company did you use and what materials were available to choose from? I’m currently modelling an Australian 73 Class loco in O scale (7mm = 1ft), and was wondering about using this process to make the bogies and some detail parts with a company called i.materialise.com.

Shapeways.com

I haven’t used them (yet) but have seen their products. the seem to do a good job a treasonable prices with good detail.

Thanks, Eric. I was looking at i.materialise. I didn’t know about shapeways. I’ll check them out. Thanks.
